    "abstract": "We demonstrate lineshape measurement of an extreme-weak amplitude fluctuating\nlight source by using the photon-counting-based second-order correlation\nspectroscopy combined with the heterodyne technique. The amplitude fluctuation\nof a finite bandwidth introduces a low-lying spectral structure in the\nlineshape and thus its effect can be isolated from that of the phase\nfluctuation. Our technique provides extreme sensitivity suited for\nsingle-atom-level applications.",
